From Scrap Tires to Premium Floors: How Recycled Rubber Flooring Is Made

Over a billion tires reach end of life every year worldwide, and rubber does not biodegrade. Flooring is one of the best second lives a tire can get: the same properties that make tires durable — impact resistance, wear resistance, weather resistance — make excellent gym floors, playground tiles and pavers.

A typical dense rubber floor tile is more than 80% rubber by weight, most of it recycled. One production line keeps thousands of tires out of landfill or open burning every month.

Step 1, collection and sorting: tires are collected, inspected and sorted by type. Step 2, shredding: whole tires pass through shredders into palm-size chips. Step 3, separation: magnets pull out steel wire, and air classification removes textile fiber — what remains is clean rubber.

Step 4, granulating and cleaning: chips are ground into granules of 1–4 mm and washed to remove dust and contaminants. Step 5, forming: the granules are mixed with a polyurethane binding agent, pressed into molds or calendered into rolls, and cured under heat and pressure. Colored EPDM granules go in at this stage for the decorative surface layer.

Buyers should know what they are actually getting. A black gym mat is usually close to 100% recycled rubber plus binder. A two-layer tile presses recycled rubber into the base and adds a virgin EPDM-rich top layer for color. A flecked roll mixes colored EPDM granules into a recycled black base.

Each design is legitimate — they simply serve different budgets and aesthetics. Ask your supplier which structure you are quoting, and ask for the recycled-content percentage in writing.

Recycled rubber has a historical reputation problem because uncontrolled crumb rubber can carry heavy metals or PAHs. Modern, regulated production controls this at the source: washed granules, tested binders, and batch laboratory testing.

Request third-party test reports covering extractable heavy metals and PAHs — toy-safety standards such as EN 71-3 are the common benchmark for playground products. A factory with nothing to hide supplies these reports before you ask twice.

No — in flooring, recycled rubber performs like new. Impact absorption, slip resistance, and wear life come from the rubber itself, and tire rubber was engineered for far harsher service than a gym floor. A correctly chosen thickness gives 8–15 years of commercial service, indoors or out.

Where virgin material genuinely matters is color stability under sunlight — that is the EPDM top layer's job, not the base's.

Does recycled rubber flooring smell? A faint rubber smell fades within days of installation; persistent strong odor signals poor washing or cheap binder — reject it. Is it suitable outdoors? Yes, with UV-stable granules and drainage-friendly designs. Can it be recycled again? Yes — old tiles can be re-ground into new products, closing the loop.
